Concept:
Buddhist epistemology (Dignaga and Dharmakirti) faced a challenge: if all things are unique, momentary particulars (*svalakshana*), how can words (which are general concepts) refer to them? To solve this, they developed a unique theory of semantics.
Step 1: The Doctrine of Apoha (Exclusion).
The Buddhist theory of meaning is called Apoha. It states that a word does not refer to a positive "universal" (like "cow-ness"). Instead, the word "cow" works by excluding everything that is "not-cow." Meaning is therefore purely negative and differential. This allows Buddhists to use language without admitting the existence of permanent, real universals, which would contradict the doctrine of Impermanence.
Step 2: Contrasting with Vedic views.
• Śabdabrahma: The Vedantic idea that Word/Sound is the ultimate reality.
• Śabdanityatva: The Mimamsa view that words/sounds are eternal.
Buddhists rejected both in favor of *Apoha*.
